ATTORNEY Patented Aug. 26,- 1930 VICTOR ODQUIST, OF YONKERS, OF NEW YORK,

NEW YORK, ASSIGNOR. TO AMERICAN can COM ANY, n. Y., A CORPORATION OF NEW JERSEY CONTAINER CLOSURE Application filed September 21, 1928 Serial No. 307,482.

This invention relates in general to closures for containers and more particularly to a container cover of thefriction plug type and associated means for positively locking the cover to the container and for sealing the same.

An object of my invention is the provision of a friction plug closure for metallic containers and improved pivotal holding lugs or turn clamps which are adapted to be held in clamping position by friction and retained in such position by a common sealing wire.

Another object of my invention is the provision of an improved turn clamp for friction plug closures which is of simple construction, strong, durable, and which pro? vides an opening seal without the necessity of perforating the metal of the clamp for such insertion.

Still another ob]ect of my invention is the provision of such an improved clamp which may be produced by a minimum number of sim le operations.

umerous other objects of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Fig. 1 is a perspective view of the upper part of one type of container to which my invention is applicable.

Fig. 2 is a fragmentary vertical cross-section taken along the lines 22 of Fig. land showing details of construction.

My invention is applicable to a variety of metallic containers having friction closures. It is especially adapt-ed, however, to containers of large size whichare usually made from heavy gauge metal stock.

To illustrate a preferred embodiment of my invention, I have shown in the drawings a cylindrical container body 11 having a top 12 secured thereto by means of a double seam 13. The body 11 has, of course, a bottom (not shown) which may be integral with the body or separate and permanently secured thereto in any suitable manner. i A '50 The top 12 inward of the double seam 13 IS for the insertion of a wire.

formed with a vertical wall 14 and a sunken panel 15 which, at its center, is cut away to form a circular opening 16 concentric with the top 12. The cut edge 17 of the panel 15 is bent downwardly and inwardly to form a curl which provides a friction seat wall 18.

A friction plug 19 is adapted to close the opening 16 and to make tight friction contact with the friction wall 18. .It comprises a cup shaped member having a flat bottom 20 and a vertical friction wall 21 which terminates'at the top into a curl or stop bead'or shoulder 22. While the frictional contact between the plug wall 21 and the friction wall 18 of the top 12 is ordinarily sufficient to produce an effective closure, the outward pressure of the contents of heavy gauge metal containers, which sometimes have to undergo very rough treatment during transportation, may become greater than the frictional engagement'of' the parts 18 and 21.

Inorder to safeguard against sucha, contingency I have provided pivotal clamping lugs 28 of an improved type. Three of these clamping" lugs are shown in Fig. 1. The number employed may vary according to the size of the container, but no less than two may be provided. Since they-are all identical in construction only one of them need be described. A lug 23 is made from a substantially rectangular piece or strip of sheet metal which is folded or bent back upon itself at its transverse center to produce a loop 24.

The free ends of the blank are overlapped I to form a straight double walled anchor part 25, which is riveted to the panel 15 by means of a rivet 26. This rivet connection is loose enough to permit pivotal movement of the clamping lug 23.] The overlapped metal of the lug 23, between the loop 2 and the anchor part 25, is bent upwardly at; an angle to the plane of the panel 15 to form a shoulder 27 andto space the loop 24 away from the panel 15 so thatthe lower wall of the loop-will make accurate frictional contact with the top surface of the stop bead 22 when the plug 2 19 has been depressed to its lowermost closing position. The bend or shoulder 27 also I tends to reenforce the clamping lugs 23 and make them slightly resilient.

While these lugs 23 will ordinarily be held in proper locking position owing to their ti ht frictional contact with the stop bead of the friction plug, the container may be handled so roughly in transit that some or all of these lugs mlght be forced out of looking position. To prevent this happening I have provided an additional locking dc ice. It comprises a Wire 28 which is adapted to be inserted and pulled through the loops 2% of the clamping lugs 23, as shown in Fig. 1. After the wire has been stretched and tightened, the free ends 29 of the Wire may be secured together and sealed by means of a lead or other suitable seal 30. It Will be readily seen that the Wire 28 not only keeps the clamping lugs 23 in proper locking position and prevents them from being forced out of such position While the container in transit, but alsoacts as a means to prevent tampering with the contents of the container until the container is opened by the ultimate consumer.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may he made in the form, construction and arrangement of the parts Without departing from the spirit'and scope'of the invention or sacril'icin'g all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

i1. Ina container, in combination, a container body having a top with an opening therein, a closure adapted to close said opening, a plurality of clamps pivotally arranged about said opening and adapted to hold said closure in closing position, each of said clamps being formed out of a one-piece blank which is folded back upon itself into loop shape and having its free ends overlapped and riveted to said top.

2. In a container, in combination, a conminer body having a top With an opening therein, a closure adapted to close said opening, a plurality of clamps pivoted in spaced arrangement about said opening and adapted to hold said closure in position, each of. said clamps comprising a strip folded upon itself and having overlapped ends held together by a pivot member, the end of said clamp opposite the overlapped ends being formed into a loop which is adapted to receive a wire seal.

3. A pivotal clamp for holding a closure upon a container, comprising a strip of material bent back upon itself at its transverse center to provide overlapping edges at one end and a looped aperture at the other end, and a pivot member adapted to pass through said overlapping edges to pivotally secure the same to a container part.

4. A pivotal clamp for holding a closure upon a container, comprising a strip of material bent back upon itself at its transverse center to provide overlapping edges at one end and looped aperture at the other end, and a rivet passing through said overlapped edges to hold them together and to provide a pivot for the clamp.
